As others have said, it's not a standard phrase. However, it's important to point out how the word heavy can be used to describe things other than weight and mass. Couples can engage in heavy conversations; students can trudge through heavy reading passages. We can be advised not to eat a heavy meal before a long swim.

Your passage doesn't even tell us what is being described – something you should be more careful about in future questions. However, I can venture guess as to what the expression might mean, based on Definition 6 in Macmillan, which says:

heavy (adj.) used about things that look ugly because they are big
heavy features (=large mouth, eyes, and nose) : He was a tall dark man, with heavy features.
